vided and this application December 27, 1956, Serial 3 Claims. (Cl. 130-5) This invention relates to husking machines and is a divisional application of my co-pending appllcation, Serial No. 443,527, filed July 15, 1954, now Patent No. 2,792,005 for Husking Machine.

It is an object of the present invention to provide a husking machine wherein the husks are drawn downwardly between the rollers by a continuous suction.

It is still another object of the present invention to provide a corn husking machine wherein the husks are drawn downwardly between the husking rolls by continuous suction devoid of any interruption or stops.

Other objects of the invention are to provide a husking machine bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efficient in operation and use.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a top plan view of a corn husking machine embodying the features of the present invention;

Fig. 2 is a vertical sectional view thereof taken along the line 22 of Fig. 1; and

Fig. 3 is a vertical sectional view thereof taken along the line 3-3 of Fig. 2.

Referring now more in detail to the drawing, there is shown a preferred embodiment of the present invention indicated generally at 40 and including a housing 41 formed along its upper portion with a relatively narrow neck 42 providing a narrow slot 43 (Fig. 2). The housing 41 is open as at 44 to permit the downward passage of the husks 45 therethrough.

A longitudinal bracket 45 has the opposite ends thereof suitably secured to the inside of the opposite ends of the housing 41 (Fig. 3) and serves to mount thereon an electric blower 46 adapted to draw the air downwardly from slot 43 and out through the outlet opening 44. A conical screen 47 is mounted above the fan 46 in suitable manner and serves to prevent the husks 45 from coming into contact with the blade portions, as will be obvious.

The open upper end of the housing 41 is integrally formed with the semicylindrical housings 48 within which are rotatably mounted the shafts 49, the opposite ends of the shafts 49 being journalled in the ends of the semicylindrical portions 48. Longitndinally spaced rollers 50, aligned laterally with each other, are keyed onto the shafts 49. Intermediate each of the rollers 50, collars 51 of less diameter than the rollers 50 are provided.

The shafts 49 extend outwardly at one end of the semicylindrical portions 48 and are each provided with a gear 52, the gears 52 being in mesh with each other whereby to rotate the rollers 50 against each other and to draw the husks 45 downwardly therebetween. The gears 52 will be driven in suitable manner. Such driving means are well known to those skilled in the art, and

will not therefore be described in detail.

Thus, in operation spaces will be provided intermediate the adjacent pairs of collars 51 permitting the air to be drawn downwardly therebetween by the suction fan 46, the housing 41 being airtight. The husks will be drawn downwardly between the rollers 50 and will also be pulled down intermediate the spaced collars 51 and permitting the solid part of the rollers to catch the husks. The

2,821,984 Patented Feb. 4, 1958 suction will draw the husks downwardly through the open spaces intermediate the collars 51. The husks 45 will be discharged to the ground through the outlet opening 44. Thus a continuous suction of air intermediate the collars 51 will be provided, drawing the husks downwardly therebetween and forcing them into more firm contact with the rollers 50, the rollers 50 stripping the husks more efliciently from the ears.

The relatively narrow slot 43 will concentrate the suction directly below the adjacent surfaces of the rolls. Thus, a constant suction is provided for drawing the husks downwardly between the open portions of the rolls. The rolls 50 will strip the husks 45 from the ears after the constant suction has drawn the husks downwardly thereagainst. The constant suction will eliminate the holding down devices commonly employed and will be more efiicient than the latter.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. A corn husking machine comprising, in combination, complementary roller means for drawing corn husks downwardly therebetween, means for driving said roller means together, a closed housing beneath said roller means, and an electric suction fan within said housing beneath said roller means, said housing defining an outlet beneath said electric suction fan, said housing above said suction fan adjacent to said roller means defining a relatively narrow slot for concentrating the suction force of said fan directly below the adjacent surfaces of said roller means, and a substantially conical screen mounted within said housing above said suction fan to prevent the husks from contacting said suction fan.

2. A corn husking machine according 'to claim 1, including a pair of substantially semicylindrical housings formed along said neck, a pair of parallel, laterally aligned shafts having opposite ends journalled in the end walls of said semicylindrical housings, longitudinally spaced rollers secured to said shafts in laterally aligned relationship with their outer faces in contact, collars intermediate said rollers of less diameter than said rollers and providing open spaces therebetween, adapted to permit the air to be sucked downwardly therethrough, and means for driving said shafts together.

3. A husking machine comprising a housing having a relatively narrow elongated inlet opening at the upper end thereof and an elongated relatively wide outlet opening at the bottom thereof, a pair of substantially semicylindrical housings formed at the upper end of said first housing, a pair of substantially parallel laterally aligned shafts having opposite ends journalled in the end walls of said semicylindrical housings, longitudinally spaced rollers secured to said shafts and in laterally aligned relationship with their outer faces in contact with each other, collars intermediate said rollers of less diameter than said rollers and providing open spaces laterally therebetween adapted to permit the air to be sucked downwardly therethrough, means for driving said shafts toward each other, an electric suction fan located within said first housing above said outlet opening thereof, and a substantially conical screen mounted within said closed housing above said suction fan whereby to prevent the husks from coming in contact with said suction fan.
